Technical analysis: Moderna stock soars 177% and Merck stock gains 12.6% on melanoma vaccine data

20 August 2026 AiTrading67 · Trade Desk Observatory Markets

The 19 August session was not written by the macro picture. It was written by a single clinical readout: Moderna stock closed 176.97% higher and Merck stock 12.60% higher after phase 3 data on the personalised melanoma vaccine the two companies developed together — a 49% reduction in the risk of recurrence or death and a 59% reduction in distant metastasis. The whole of US biotech moved behind them, and Wall Street snapped a three-day losing run.

In the cards below you will find the technical analysis of the names that moved the day — Moderna, Merck, CRISPR Therapeutics, Marvell, Broadcom, Nvidia and Coinbase on Wall Street, Stellantis, STM, Intesa Sanpaolo and Leonardo on the Milan market — and for each one where our model stands, long or short, with the date the signal fired. We open with this week's new buy signals and close with SPY against QQQ, the two US ETF baskets, which finished yesterday with opposite signs.

How I read itThe cohort has stopped deteriorating as a block and started to separate, and health care is what makes the difference. CRISPR Therapeutics is up 11.69% from Friday's signal after yesterday's 12.91% jump, the best result of all thirty. The short horizon remains the variable to watch: three days ago only one new signal in thirty had the daily reading in sell, today seventeen do. In swing trading, on a cohort this young, any trading strategy comes down to a sizing decision: you take the slice you are willing to see underwater for a few sessions, or you wait for Friday's close.

Health care and biotech

Health care technical analysis: Moderna stock up 177%, Merck stocks up 12.6%

The phase 3 trial of the personalised melanoma vaccine — intismeran autogene, built from each patient's own tumour — showed, in combination with immunotherapy, a 49% reduction in the risk of recurrence or death and a 59% reduction in distant metastasis. Moderna closed 176.97% higher, with market capitalisation moving from roughly 25 to 69 billion dollars, and Moderna stocks ended the day as the most traded story on the tape; Merck &, the programme's partner, gained 12.60%.

The wave carried the whole sector: Hims & Hers Health up 13.51%, Recursion Pharmaceuticals up 13.27%, CRISPR Therapeutics up 12.91%, Novavax up 10.84%, Beam Therapeutics up 9.41%, Danaher up 5.97%, Amgen up 4.02%, Regeneron Pharmaceuticals up 3.78%, Pfizer up 3.63%. Short sellers took roughly 5.5 billion dollars in paper losses in a single day.

How I read itWe had been positioned in the right sector for months, and yesterday we collected rather than chased. Health Care US, the US health care ETF, has been long since 26 May and is up more than 17% from the signal; Regeneron Pharmaceuticals carries over 26% since early July, Amgen over 24% since June, Merck & over 24% since May, and CRISPR Therapeutics 11.69% from a signal born on Friday. No technical model can anticipate a clinical readout of this size. What a model can do is already be in the sector when it lands, and this time we were. On Moderna we were short, and the exit level we publish had been taken out on 13 August, seven sessions before the jump: anyone following it was already out. The weekly Inversion Point has now flipped to buy on the bar still forming, so the signal is long and provisional until Friday's close.

Semiconductors

Semiconductor stocks: the Marvell-Google deal rewrites custom silicon

Marvell Technology granted Google a warrant to buy up to almost 59 million shares at 206.58 dollars — a potential value near 12.2 billion — as part of an agreement to develop custom chips for artificial intelligence: inference accelerators, storage, networking and memory controllers. Vesting tranches are tied to Google's chip purchases and run through fiscal 2033; if the targets are met the deal could be worth roughly 120 billion in multi-year sales. The shares closed 9.85% higher.

The bill landed on its direct rival in that same market: Broadcom fell 4.61%, and Broadcom stocks closed at the bottom of the large-cap chip group. Around them the sector felt the squeeze of high yields and rising crude — Advanced Micro Devices down 3.71%, Intel down 4.02% — while NVIDIA held the line, shedding less than a point ahead of its 26 August results.

How I read itOur model has been almost entirely short this sector since mid-July, and the positions are working: we are short STMicroelectronics RegS from 13 July with more than 23% from the signal, Infineon Technologies from the same day with nearly 16%, Intel with over 2%, and semiconductor ETF, the semiconductor ETF, just above break-even. Where we are long the day went against us: on Broadcom, a signal born on 3 August, and on NVIDIA, which reaches its results with the position slightly underwater. Marvell Technology is the most unusual case on the page: the short has been open since 13 July, but the weekly Inversion Point — the level that decides for us whether a trade still exists — has just flipped to buy on the bar still forming, on the very day the shares rose 9.85%. Provisional: it confirms or dies on Friday.
Our system · Marvell Technology short (G / P) · Broadcom long (G / P) · Advanced Micro Devices long (G / P) · NVIDIA long (G / P) · Intel short (G / P) · Micron Technology short (G / P) · STMicroelectronics RegS short (G / P) · semiconductor ETF short (G / P)

Bitcoin clears 68,000 dollars: the digital complex comes back to life

After several difficult weeks the digital complex staged a sharp rebound. Bitcoin cleared 68,000 dollars, up 6% with an intraday high near 69,750, dragging Strategy up 12.68%, Coinbase Global up 9.55%, MARA up 7.70% and Riot Platforms up 2.49%.

Three catalysts arrived together: the doubling of long-dated debt buybacks announced by the US Treasury from September, the market regulator's 18 August proposal for a first set of rules covering token offerings, and a White House meeting between the heads of the two regulators and industry operators. The complex nonetheless remains deeply negative for the year to date.

How I read itHere our model sits entirely on one side, and it is a stance built over months that holds even after an adverse session. We are short Strategy from 26 May with more than 52% from the signal, MARA from 13 July with over 10% and Riot Platforms from 6 July with over 8%: yesterday those three gave something back, but the cushion already banked turns it into noise. On Coinbase Global the short has been open since 1 June and sits just under five points underwater. The right way to read a 6% bounce in a cryptocurrency on regulatory news is to look at what money was doing: on both companies the weekly flow is still leaving, and a price that rises while money leaves contradicts its own move.
Our system · Strategy short (G / P) · Coinbase Global short (G / P) · MARA short (G / P) · Riot Platforms short (G / P)

Baidu stock and Alibaba stock: advertising fades, cloud runs

Baidu, which reported on 18 August, confirmed a difficult transition: revenue down 4% year on year at 31.3 billion renminbi and online advertising down 19%, but with AI cloud growing 50% and the graphics-card segment up 283%. The shares recovered 2.20% yesterday. The group is moving towards a dual primary listing in Hong Kong, with an extraordinary meeting scheduled for 26 August.

Alibaba closed 0.59% higher and reports today, Thursday 20 August, alongside Walmart.

How I read itOn Baidu our model has been short since 8 June and the gain from the signal is above 24%: eleven weeks in which the chart anticipated what the accounts later certified. On Alibaba we sit on the other side, long from 13 July with more than 12% from the signal, and the position reaches today's results with all three horizons in agreement. On the eve of a print our approach does not change direction: it changes size. On Walmart we are short from 26 May, with the position broadly flat going into the numbers.

MILAN MARKET
Piazza Affari

Milan market technical analysis: Stellantis stock up 5.9%, banks in retreat

The FTSE MIB gave up 0.75% in a directionless session, and the movement was all internal to the index. Stellantis Milano led at plus 5.90%; the banking block trailed, with Monte dei Paschi down 2.19%, Mediobanca down 2.01%, Intesa Sanpaolo down 1.37% and UniCredit down 1.21%, in the wake of a European sector that shed 1.41%. Also lower: STMicroelectronics down 3.02% on the semiconductor wave, Fincantieri down 1.66%, Leonardo down 1.17%, Avio down 1.02% and Nexi down 0.60%.

On the corporate front attention stays fixed on banking consolidation: Intesa Sanpaolo's exchange offer for Monte dei Paschi, a 30.6 billion transaction, and talk of moves around Banco BPM and Banca Generali.

How I read itWe have been long Italian banks since April, and one sour session does not dent positions built in the spring: Mediobanca carries more than 36% from the signal, Banco BPM over 31%, Monte dei Paschi over 28%, Intesa Sanpaolo almost 20%, UniCredit over 14% and FinecoBank over 13%. On the two names at the extremes of the day the model has been on the right side since the summer: we are short Stellantis Milano from 8 June with 27% from the signal — yesterday's 5.90% rise ate into that margin without putting it in question — and short STMicroelectronics from 13 July with more than 22%. On Leonardo we are long from 27 July with 6% from the signal, and Italian defence remains the theme with the broadest sector coverage on the exchange.

EUROPE
London and Frankfurt

AstraZeneca stock: the denied merger and a share price that barely moves

London barely moved, with the FTSE 100 closing just 15 points higher. The case of the day remains AstraZeneca and the possible merger with Bristol Myers Squibb, a transaction of roughly 400 billion dollars that has been discussed since the start of the month: during the session a source close to the file denied that talks are under way, and the shares closed 2.07% higher. GSK also did well, up 1.48%.

In Frankfurt the picture was the semiconductor one: Infineon Technologies shed 3.95%, while SAP gained 1.86%.

How I read itWe have been short Infineon Technologies since 13 July and the gain from the signal is above 15%: yesterday widened a position already well in profit, and it is the best European result of the day. On SAP we are long from 27 July with almost 18%, so yesterday's rise worked there too. On AstraZeneca our short has been open since 13 July and remains more than four points in profit, even though yesterday took something off it. On a share moving to a denied merger rumour the chart says little: when the corporate flag is doing the talking, the flag wins, and size should be cut accordingly.

EUROPEAN INDICES
The four baskets side by side

European indices: the same signal for twenty weeks, and one of the four is still far from its record

All four European baskets carry a buy signal opened in the spring, with very different results. FTSE MIB leads with 13.40% from the signal of the week of 7 April and sits 2.62% below its own record; DAX carries 5.43% from 13 April and is 1.61% below its high; CAC 40 5.13% from 7 April and is 2.82% below. FTSE 100, the London basket, has the same signal from the same day and has produced 1.23%.

Yesterday the moves were tiny and almost indistinguishable: Milan gave up 0.75%, Paris and Frankfurt closed all but flat, London rose 0.19% and was the best of the four for a second straight session.

How I read itThe divergence worth watching is still London's, and it reads in two stages. The British basket is 8.41% below its own record against 1.6-2.8% for the other three: it is the only one that never truly joined the spring rally, and in twenty weeks of signal it has produced barely more than a point. Precisely because it is not extended, though, it is also the most sheltered when selling comes from rates or from technology — and two sessions now have shown it. The same structure that has been a flaw is working as protection, and that is the kind of information you only see by reading the four together. The gap between each basket and its own weekly Inversion Point runs from half a point to 1.7 points: none of the four has much room, and next week matters more than this one.

INSTRUMENTS
Baskets and sectors

The ETFs that moved the session: from the gold ETF to the US healthcare ETF

The session reads better through the instruments than through single names. Sanita USA, the US healthcare ETF, gained 3.51% and was the best sector of the day; ETF sull'oro, the gold ETF, rose 3.84%, lifted by the return of the rate-cut trade after the US Treasury announcement. In Europe the basic resources ETF added 3.28% and is the continent's best basket over the month as well, at 11.57%.

At the other end ETF sui semiconduttori, the semiconductor ETF, lost 2.21% and Tecnologia USA, the US technology ETF, 1.07%: the latter is down 3.35% on the week and still up 4.51% over the month.

How I read itThe two baskets that ran yesterday are exactly the two we were already positioned in, and not since yesterday. We have been long the US healthcare ETF since 26 May with more than 17% from the signal, long the gold ETF since 3 August, and long the US energy ETF since 13 July with over 10%. On the semiconductor ETF we sit short from 13 July and the session worked for us. The one that deserves caution is the US technology ETF: the buy signal was born on Friday and is already 3.35% underwater with the short horizon against it, and its two twins on the same sector tell the identical story. Five different baskets, one single position: one of them is enough.

Li Auto Long

NVIDIA Long

Thursday 27 August

Autodesk Long

How I read itThe real hinge is 26 August, when NVIDIA, Salesforce, CrowdStrike and two others report on the same day: a concentration that turns that session into an index-level event on the artificial intelligence theme. On NVIDIA our buy signal has been open since 3 August and is slightly underwater, with the sector having just shed another point: this is the situation where the result matters more than the chart. On the measurement we ran in house, entering with an active signal ahead of a print returns as much as entering without one, but with twice the dispersion. Earnings are therefore a risk management decision about size rather than a reason to enter. Among the names on the calendar the strongest positions are HP, more than 16% from the signal, and Intuit, almost 15%.

THE COMPARISON
The two US baskets

SPY and QQQ technical analysis: same market, same day, opposite signs

S&P 500, the S&P 500 ETF, gained 0.21% and Invesco QQQ Trust, the Nasdaq 100 ETF, lost 0.20%. Weights explain the divergence in full: the first carries 9.47% in health care against the second's 5.11%, so it holds almost twice the exposure to the sector that rose 3.51% yesterday; and it carries 32.91% in technology against 50.54%, that is two thirds of the exposure to the sector that fell 1.07%.

Their ages remain just as different. The S&P 500 basket is in the twentieth week of its signal, up 13.19% from entry with all three profit-taking windows already banked; the Nasdaq basket is in its second, down 2.05% with every window still ahead. The first sits 1.32% below its record, the second 4.35%.

How I read itThe story of the day is not the difference in sign, it is what they share. Both still have the daily Inversion Point above the price, therefore in sell, and both remain under the floor of their own congestion zone, the band inside which our system proposes no entries. The S&P 500 basket has come back to within a tenth of a point of that edge, while the Nasdaq one sits almost half a point below it and has settled exactly on the upper edge of the Ichimoku cloud. On the weekly frame neither has moved: the buy signal is open on both, with the weekly Inversion Point below the price by 1.92% on the former and 3.42% on the latter. It is a divergence between horizons, and it resolves at Friday's close.

The desk's take

When a single clinical readout makes the day, the macro takes a back seat

The underlying picture eased across the board, and that is the context for everything else. The four gauges of tension fell together — equity volatility by 6.0%, bond volatility by 5.0%, the BTP-Bund spread by 1.5% and tail risk by half a point — the day after long-dated yields stopped climbing. Over the four-week window all four were already lower: now the short frame has realigned with the long one.

The two most violent moves outside equities say the same thing from two sides. Gold gained 4.4% in a single session and the dollar lost 0.8%, both well beyond their normal range: the rate-cut trade, which looked deflated in midweek, came back to life when the US Treasury said it would buy more long-dated debt. Crude, by contrast, moved barely a point, even though tensions around the Strait of Hormuz have led the front pages for days.

The measure to keep an eye on over the coming days is market participation, the gauge of how many shares rise alongside the index: it is in a third day of decline, but yesterday it gave up less than a point against three and a half the day before, so the fall is slowing. Over the long window it is still up 14%. A rally with broadening participation stands on many legs; when participation withdraws, the legs get counted, and that is the kind of measure that in our ai trading weighs more than any single earnings print.

What you find here. If you are trying to understand how to manage risk in trading — stops, break-even stops, trailing, and the declaration of stops that have been taken out — or how to read chart patterns (double bottoms, Bollinger bands, the Ichimoku cloud, price action trading), this is the desk's trading journal: published every morning before the US premarket, with our model's position on every instrument mentioned.
